Effectiveness of telaprevir or boceprevir in treatment-experienced patients with HCV genotype 1 infection and cirrhosis.

BACKGROUND & AIMS: We investigated the effectiveness of the protease inhibitors peginterferon and ribavirin in treatment-experienced patients with hepatitis C virus (HCV) genotype 1 infection and cirrhosis. METHODS: In the Compassionate Use of Protease Inhibitors in Viral C Cirrhosis study, 511 patients with HCV genotype 1 infection and compensated cirrhosis who did not respond to a prior course of peginterferon and ribavirin (44.3% relapsers or patients with viral breakthrough, 44.8% partial responders, and 8.0% null responders) were given either telaprevir (n = 299) or boceprevir (n = 212) for 48 weeks. We assessed percentages of patients with sustained viral responses 12 weeks after therapy and safety. This observational study did not allow for direct comparison of the 2 regimens. RESULTS: Among patients given telaprevir, 74.2% of relapsers, 40.0% of partial responders, and 19.4% of null responders achieved SVR12. Among those given boceprevir, 53.9% of relapsers, 38.3% of partial responders, and none of the null responders achieved SVR12. In multivariate analysis, factors associated with SVR12 included prior response to treatment response, no lead-in phase, HCV subtype 1b (vs 1a), and baseline platelet count greater than 100,000/mm(3). Severe adverse events occurred in 49.9% of cases, including liver decompensation, severe infections in 10.4%, and death in 2.2%. In multivariate analysis, baseline serum albumin level less than 35 g/L and baseline platelet counts of 100,000/mm(3) or less predicted severe side effects or death. CONCLUSIONS: Relatively high percentages of real-life, treatment-experienced patients with HCV genotype 1 infection and cirrhosis respond to the combination of peginterferon and ribavirin with telaprevir or boceprevir. However, side effects are frequent and often severe. Baseline levels of albumin and platelet counts can be used to guide treatment decisions. ClinicalTrials.gov number: NCT01514890.

Plasma apolipoprotein H limits HCV replication and associates with response to NS3 protease inhibitors-based therapy.

BACKGROUND & AIMS: Chronic infection with HCV remains a public health problem with approximately 150 million people infected worldwide. HCV intersects with lipid metabolism for replication and entry; and plasma concentrations of apolipoproteins have been identified as predictors for response to therapy. Herein, we conducted a screen of plasma proteins, including all apolipoproteins, to identify correlates of response to pegylated-interferon/ribavirin (PR) and HCV non-structural protein 3 (NS3) inhibitors (i.e., telaprevir/boceprevir) therapy in treatment-experienced cirrhotic patients from the ANRS CUPIC cohort. METHODS: We analysed 220 baseline plasma protein concentrations in 189 patients using Luminex technology and analyzed results. RESULTS: We identified baseline levels of apolipoprotein H (apoH) as a surrogate marker for sustained virological response (SVR). Notably, increased plasma concentration of apoH, used in combination with known clinical parameters, established a robust model with improved classification of patients as likely to achieve SVR (AUC = 0.77, Se = 66%, Sp = 72%, NRI = 39%). Moreover, we provide mechanistic information that indicates a previously unidentified role for apoH during viral entry. Using a human liver slices HCV infection model, we demonstrate that apoH limits replication. CONCLUSION: These data support testing of new biomarker strategies for the management of cirrhotic HCV patients and expand our understanding of how apoH may intersect with HCV infection.

Antiviral therapy is associated with a better survival in patients with hepatitis C virus and B-cell non-Hodgkin lymphomas, ANRS HC-13 lympho-C study.

Hepatitis C virus (HCV) infection increases the risk of B-cell non-Hodgkin lymphomas (B-NHL). Antiviral treatment (AT) can induce hematological responses in patients with marginal zone lymphomas (MZL). The ANRS HC-13 Lympho-C study aimed at a better understanding of the impact of AT on HCV associated B-NHL. This multicentric study enrolled 116 HCV-positive patients with B-NHL between 2006 and 2012. Cytological and histological samples were collected for centralized review. At lymphoma diagnosis, median age was 61 years and gender ratio M/F was 1. Cytohistological distribution was marginal zone lymphoma (MZL) n = 45 (39%), diffuse large B-cell lymphoma (DLBCL) n = 45 (39%), and other types n = 26 (22%). MZL patients had more frequent detection of rheumatoid factor (68% vs. 35%; P = 0.001) and more frequently mixed cryoglobulinemia (74% vs. 44%; P = 0.021) than patients with DLBCL. Among patients receiving AT, a sustained virologic response was achieved in 23 of 38 (61%) patients with MZL and in 9 of 17 (53%) with DLBCL (P = 0.42). Three-year overall survival (OS) and progression-free survival were 78% 95%CI [63-88] and 64% [48-76], respectively, without difference between cytohistological groups. Outcome analysis showed a favorable association between OS and AT in all patients (P = 0.05) and in the subgroup of MZL patients only (P = 0.04). Our data support that AT improves the outcomes of HCV-associated NHLs. The impact of new AT regimen with protease inhibitor needs to be investigated in this setting.

Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.

BACKGROUND & AIMS: In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed. METHODS: A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72). RESULTS: Fifty-one patients (49 men, median age 46 years, range: 32-65), were included. Median duration of HIV, HBV infections and TDF therapy was 10.3 (0.6-22), 9.8 (0.5-16), and 3.3 (0.5-6.8)years, respectively. Median baseline CD4 count was 506 (175-1316)/mm(3). HIV viral load was <50 copies/ml in 49 (96%) patients. Nine (18%) patients stopped PegIFN prematurely. Ten (20%) patients experienced HBeAg loss at W72 and four (8%) patients had a HBV sustained response. No HBs seroconversion was observed. Only patients with more than 350 CD4/mm(3) at baseline achieved HBe loss. HBeAg level >10 PEIU/ml at W12 or a quantitative HBsAg decline <0.5 log IU/ml at W24 had 100% and 84% negative predictive values for response, respectively. CONCLUSIONS: 48-week PegIFN additional therapy to cART including TDF did not significantly increase the HBe seroconversion rate, despite an HBeAg loss in 20% of the patients. HBe and HBs kinetics may nevertheless be of help in tailoring and optimising this strategy.

Triple therapy in treatment-experienced patients with HCV-cirrhosis in a multicentre cohort of the French Early Access Programme (ANRS CO20-CUPIC) - NCT01514890.

BACKGROUND & AIMS: In phase III trials, the safety profile of triple therapy (pegylated interferon/ribavirin with boceprevir or telaprevir) seems to be similar in HCV treatment-experienced cirrhotic and non-cirrhotic patients, but few cirrhotics were included. We report the week 16 safety and efficacy analysis in a cohort of compensated cirrhotics treated in the French Early Access Programme. METHODS: 674 genotype 1 patients, prospectively included, received 48 weeks of triple therapy. The analysis is restricted to 497 patients reaching week 16. RESULTS: A high incidence of serious adverse events (40.0%), and of death and severe complications (severe infection or hepatic decompensation) (6.4%), and a difficult management of anaemia (erythropoietin and transfusion use in 50.7% and 12.1%) were observed. Independent predictors of anaemia < 8 g/dl or blood transfusion were: female gender (OR 2.19, 95% CI 1.11-4.33, p=0.024), no lead-in phase (OR 2.25, 95% CI 1.15-4.39, p=0.018), age ≥ 65 years (OR 3.04, 95% CI 1.54-6.02, p=0.0014), haemoglobin level (≤ 12 g/dl for females, ≤ 13 g/dl for males) (OR 5.30, 95% CI 2.49-11.5, p=0.0001). Death or severe complications were related to platelets count ≤ 100,000/mm(3) (OR 3.11, 95% CI 1.30-7.41, p=0.0105) and albumin <35 g/dl (OR 6.33, 95% CI 2.66-15.07, p=0.0001), with a risk of 44.1% in patients with both. However, the on-treatment virological response was high. CONCLUSIONS: The safety profile was poor and patients with platelet count ≤ 100,000/mm(3) and serum albumin <35 g/L should not be treated with the triple therapy.

Coronary heart disease is associated with a worse clinical outcome of hand osteoarthritis: a cross-sectional and longitudinal study.

OBJECTIVE: To determine whether cardiometabolic factors are associated with hand osteoarthritis (HOA) symptoms, radiographic severity and progression in a post hoc analysis of the phase III Strontium ranelate Efficacy in Knee OsteoarthrItis triAl (SEKOIA) trial, designed to determine the effect of strontium ranelate on knee osteoarthritis (OA). METHODS: Among the 1683 patients randomised in the SEKOIA study, 869 with radiographic HOA at baseline (rHOA≥2 joints with Kellgren-Lawrence grade ≥2) were included in a cross-sectional analysis. For longitudinal study, we included only the 307 patients with rHOA at baseline from the placebo group. We evaluated whether baseline symptomatic HOA, radiographic severity and clinical and rHOA progression were associated with coronary heart disease and/or metabolic diseases (obesity, diabetes and hypertension, dyslipidaemia) by multivariate regression analysis. RESULTS: At baseline, 869 patients (72% women) were included in the cross-sectional analysis; 26% were symptomatic. On multivariate analysis, symptomatic HOA was associated with coronary heart disease (OR 3.59, 95% CI (1.78 to 7.26)) but not metabolic diseases. After a mean follow-up of 2.6 years, for the 307 participants in the placebo group, on multivariate analysis, worse clinical HOA outcome was associated with coronary heart disease (OR 2.91, 95% CI (1.02 to 8.26)). The slow radiographic progression did not allow for revealing any associated factors. CONCLUSIONS: Symptomatic HOA and worse HOA clinical course are associated with coronary heart disease. These results strengthen the systemic component of HOA and the association between OA pain and cardiac events. TRIAL REGISTRATION NUMBER: ISRCTN41323372.

Effect on HBs antigen clearance of addition of pegylated interferon alfa-2a to nucleos(t)ide analogue therapy versus nucleos(t)ide analogue therapy alone in patients with HBe antigen-negative chronic hepatitis B and sustained undetectable plasma hepatitis B virus DNA: a randomised, controlled, open-label trial.

BACKGROUND: Findings from uncontrolled studies suggest that addition of pegylated interferon in patients with HBe antigen (HBeAg)-negative chronic hepatitis B receiving nucleos(t)ide analogues with undetectable plasma hepatitis B virus (HBV) DNA might increase HBs antigen (HBsAg) clearance. We aimed to assess this strategy. METHODS: In this randomised, controlled, open-label trial, we enrolled patients aged 18-75 years with HBeAg-negative chronic hepatitis B and documented negative HBV DNA while on stable nucleos(t)ide analogue regimens for at least 1 year from 30 hepatology tertiary care wards in France. Patients had to have an alanine aminotransferase concentration of less than or equal to five times the upper normal range, no hepatocellular carcinoma, and a serum α fetoprotein concentration of less than 50 ng/mL, normal dilated fundus oculi examination, and a negative pregnancy test in women. Patients with contraindications to pegylated interferon were not eligible. A centralised randomisation used computer-generated lists of random permuted blocks of four with stratification by HBsAg titres (< or ≥2·25 log10 IU/mL) to allocate patients (1:1) to receive a 48 week course of subcutaneous injections of 180 µg per week of pegylated interferon alfa-2a in addition to the nucleos(t)ide analogue regimen or to continue to receive nucleos(t)ide analogues only. The primary endpoint was HBsAg loss at week 96 by intention-to-treat analysis. This trial is closed and registered with ClinicalTrials.gov, number NCT01172392. FINDINGS: Between Jan 20, 2011, and July 18, 2012, we randomly allocated 185 patients (92 [50%] to pegylated interferon and nucleos(t)ide analogues and 93 [50%] to nucleos(t)ide analogues alone). We excluded two patients from the pegylated interferon plus nucleos(t)ide analogues group from analyses because of withdrawal of consent (one patient) or violation of inclusion criteria (one patient). At week 96, loss of HBsAg was reported in seven (7·8%) of 90 patients in the pegylated interferon plus nucleos(t)ide analogues group versus three (3·2%) of 93 in the nucleos(t)ide analogues-alone group (difference 4·6% [95% CI -2·6 to 12·5]; p=0·15). 85 (94%) of 90 patients started pegylated interferon, three (4%) of whom had a dose reduction and 17 (20%) had an early discontinuation of pegylated interferon (seven [41%] for serious adverse events). Grade 3 and 4 adverse events were more frequent in the pegylated interferon plus nucleos(t)ide analogues group (26 [29%] grade 3 adverse events; 19 [21%] grade 4 adverse events) than in the nucleos(t)ide analogues-alone group (three [3%] grade 3; six [6%] grade 4). INTERPRETATION: Addition of a 48 week course of pegylated interferon to nucleos(t)ide analogue therapy in patients with HBeAg-negative chronic hepatitis B with undetectable HBV DNA for a least 1 year was poorly tolerated and did not result in a significant increase of HBsAg clearance.
